JAMES GAGE. BAILEY, OF RICHMOND HILL, ONTARIO, CANADA.

MAKING PLOWCOLTERS..

SPECIFICATION forming'part of Letters Patent No. 358,828, vdated March .8, 1887.

' Application filed September 4, 1886. Serial No. 212.760. (No model.)

To all whom t may concern:

Be it known that I, JAMEs GAGE BAILEY,

of the village of Richmond Hill, in the county drawings, in which- Figure l is a view of the metal bar from which the colter is to be made, showing the surfaceof the side which has the depression, and also a crosssection of the same bar. Fig. 2 represents another form ofthe bar from which the colter is to be made, showing the surface which has the depression, and also a cross section of the same bar. Fig. 3 is a view of the finished colter with cross-sections of the same.

Similarletters re'fer to similar parts throughout the several views.

ln the manufacture of ploW-colters 'I use a metal bar, A, Fig. l, the one side of which has the center portion of its surface depressed in the form of an inclined plane, said depression beginning at or near to one edge, a, at the surface, and continuing to the point c, below the plane of the surface near to the opposite edge, d. Thisbar is the proper shape for the upper portion of the colter. To form its cutting-edge, I turn outward a sufficient portion of the edge d e, the angle ofthe inclined plane surface b c being such as, continued on the portion ofthe edge d e turned outward, is suitable for the formation ofthe said Cuttingedge. An equivalent process is by using a metal I bar, A, Fig. 2, one edge, a g, of which is cfa thickness suitable for the back of the colter, and the opposite edge, f, of a proper thickness for the cutting-edgef, thus having one side, a f, ofthe bar inclined toward the plane of the opposite side. This bar is the proper shape for the blade of the colter. To form the upper part of the colter, I turn a suliicient portion of the sharp edge f in such a manner as to make it correspond with the opposite edge, ag, in thickness. Either process produces the same colter as in Fig. 3.

It will be noticed that a cross-section of the t upper portion of the finished colter, Fig. 3, corresponds with a crosssection of the bar A, Fig. 1, and that a cross-section ofthe blade of the inished colter corresponds with a crosssection of the metal bar A shown in Fig` 2; also, that thel bar shown in Fig. l is of the same Width as the upper portion ofthe nished colter, while the metal bar shown in Fig. 2 is of the same width as the blade of the iinished colter.

I do not clai rn any advantage over the ordinary colter in regard to its working principle; but

What I do claim as myinvention, and which I desire to secure by Letters Patent, is-

l. A plowcolter the portion above the blade of which is hollowed on one side, substantially yas described, and for the purpose specified.

2. A metal bar, A, of the forni represented in Fig. 1, substantially as4 described, for use in the manufacture of plow-colters.

' 3. A plow-colter made from a metal bar, A, of the form represented in Fig. 1, substantially as described, and in the manner specified.
